HOSE AND PIPE COUPLING.

SPECIFICATION forming part of Letters Patent N 0. 736,057, dated August-11, 1903.

Application filed October 2,1902. Serial No. 125,697. (No model.)

To aZZ whom it may concern:

Be it known that I, ALBERT BEATTY, a citizen of the United States ofAmerica, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in Hoseand Pipe Couplings, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to certain newand useful improvements in hose andpipe couplings; and the invention has for its object to provide acoupling particularly adapted for connecting suction-hose to a fire-plugor to an engine and for use in coupling sections of a water-line hosetogether in an efficient manner as well as in anextremely short space oftime.

The invention relates to that class of devices in which eccentrics orlevers are used for forcing the abutting ends of the hose into intimateunion or for forcing the coupling on the end of the suction-hose intounion with the coupling of the fire-plug or fire-engine.

In describing the invention in detail reference is, had to theaccompanying drawings, forming a part of this specification, and whereinlike numerals of reference indicate like parts throughout the severalviews, in which- Figure l is a top plan View of my improvedhose-coupler, showing the same applied in position for coupling asuction-hose up to the fire-plug. Fig. 2 is a detail perspective view ofthe form of coupling employed in connection with the suction-hosedetached there.-

from. Fig. 3 is a longitudinal sectional view of a part of one of thelever-arms. Fig. at is a top plan View of a modified form of coupling,more particularly adapted for coupling sections of Water-line hosetogether, a portion of the union between the two sections of hose beingin section. Fig. 5 is a detail perspective View of the form of couplingshown in Fig. 4. detached from the hose.

Heretofore it has'generally been the practice to connect thesuction-hose which leads from the fire-plug to the fire-engine by meansof set-screws which fasten the union or coupling carried by thesuction-hose to the fireplug, and similarly the other end of thesuction-hose is connected to the pump of the engine. This operation iscomparatively slow, it requiring a wrench to make the coupling, and asit is of extreme importance in case of fire that the engine be coupledup to the water-supply at the very earliest possible moment and alwayspreferably by the time the water-line hose is reached for use it is theobject of my invention to provide means whereby this coupling may bequickly effected. To this end I provide in opposite sides of the union1, carried by the end of the suction-hose 2, studs or pins 3, which actas trunnions for a pair of lever-arms 4, provided adjacent to'theirinner end with openings or eyes 5to receive the studs or pins 3. In Fig.1 I show the-union 1 provided with set-screws 6, employed for fasteningthis union to the fireplug in the ordinarymanner. With my invention I donot-change the union in this respect and do not require the removaltherefrom even of the set-screws 6. The studs or pins 3 may be threadedor tapped into the opposite sides of the union at very small cost andwhen not in use may be removed or cut OE, and the union remains in itsoriginal form. The lever-arms 4 are connected together at v the forwardend by a connector bar or strap 7, which forms a grip for operating theleverarms 4, and to this end it is preferably slightly inclined-that is,oneedge thereof lying on aplane below the other edge-whereby the fingersmay be inserted under the bar between the same and the hose in order topermit the uncoupling of the device, and this bar also serves as anelement on which pressure may be exerted to force the coupling into thecoupled position. The lever-arms 4. are each provided near their inn orends with a slot 8, in which is mounted the adjustable bolt 9. providedon its inner face with serrations or teeth 10, which engage with theserrated or toothed inner face 11 of the bars 4, whichserrated ortoothed portion is above and below the slot 8. The shank of the bolt 9has a square or rectangular portion 12, which fits in the slot 8, andthe bolts are held in position by means of a suitable nut-such, for

The head of this bolt is preferably the eyes 15, formed on the end ofthe droplevers 16, these levers being provided at their outer ends witha hook 17 and connected together near their outer ends by the connectorbar or strap 18, attached to the levers in any suitable manner. In orderto space the droplever 16 a suitable distance away from the levers 4, Iprovide washers 19 on the bolts 9, as clearly seen in Figs. 1 and 3 ofthe drawings. The hooked ends 17 of the levers 16 are adapted to engageabove the studs or pins 20, which are threaded or tapped into the nippleof the fire-plug 21. With this construction just described it will beevident that the manner of connecting may be reversedthat is, the hooks,which are shown on the ends of the drop-levers 16, may be provided onthe ends of the levers 5 and eyes provided in lieu of hooks on the endsof the drop-levers. In the present showing, however, it will be observedthat the coupling is carried by the suction-hose, and when it is desiredto couple the said hose to the fireplug the lever-arms 4 are moved to asubstantially V position, which will permit the engagement of the hooks17 with the studs or pins 20, and as the lever-arm's 4 are forceddownwardly into the locked position by pressure upon the connecting-bar7 the nipple of the union will be forced into engagement with the nippleof the plug, the one inclosing the other, and as the lever-arms 4 reachthe horizontal position, or slightly past the horizontal position, thecoupling is securely and effectually locked to the plug. It will beobserved that by simply loosening the wingnuts 14 and shifting the bolts9 in the slots 8 toward the inner end of the lever-arms and toward theouter ends thereof the force with which the one union is engaged withthe other is varied.

In Figs. 4 and 5 I show the same embodiment of my invention with butslightly-different construction more particularly adapted for use inconnecting water-line hose,

though either the construction shown in these views or that shown inFigs. 1, 2, and 3 may.

be employed for connecting the suction-hose to the fire-plug and to theengine and also for connecting water-line hose. In the showing in Figs.4 and 5 the drop-levers 16 are shown provided on their ends with bosses17', having openings therethrough to engage the studs or pins 20', whichare threaded or tapped into opposite sides of the union 21. In theordinary manner of connecting water-line hose together the section 22 ofthe union carries a rotatable ring 23, and the section 21 carries anextension or nipple 24. The coupling is ordinarily made by having thenipple 24 threaded to engage with the threads of the interior of therotatable ring 23, a wrench, usually in the form of a spanner-wrench,being employed for rotating this ring to join the union together. Foraccommodation of this spanner-wrench the ring 23 is provided with studsor pins 3, and I therefore employ react? these pins or studs withoutchange in connection with myimproved coupler. Where the coupling ismanufactured especially, the threads on the nipple 24 and those in thering 3 will be dispensed with, and where my improved coupling is to beapplied to the union already constructed I may remove the threads fromthe interior of the ring, which will permit the nipple 24 to enter thering Without threading. The other ends of the drop-levers 16 arepivotally connected to trunnion-burs 9, through which operate thethreaded rods 4, serving the purpose of the lever-arms for effecting thecoupling. These rods are provided with grips 5 at their inner ends,which have seats to receive the studs or pins 3, and the rods at theirouter ends are threaded through bosses 6, carried by the connecting baror strap 7, which is of a similar form of construction to the connectingbar or strap 7 and is held on the rods 4 by nuts 8 at each side of thebosses 6'. Adjustment of the rods 4, comprising the lever-arms in thisconstruction, is had by means of the adjusting-nuts 14, mounted on thesaid rods 4 between the trunnion-bur 9' and the grip ends 5 of saidrods.

In operation of this device the ends 17 of the drop-levers 20 areengaged with the studs or pins 20, and the grip ends 5 engage with thestuds or pins 3. When the lever-arms 4 are forced downwardly to thehorizontal position by pressure on the connecting-bar 7, the nipple end24 is drawn into the ring 23 in sliding engagement with a gasket 25,usually arranged within the ring 23. By adjustment of the nuts 14' thelever-arms 4 may be adjusted so as to regulate the adjustment or to takeup wear on the gasket or washer 25.

The coupling, it will be observed, is carried by the one section of thehose when the device is uncoupled, and the insertion of the othersection of the hose into position and the forcing down of the lever-armsare all that is required to effect the coupling.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is
